To all whom it may concern: 1.

Be it known that 1, CHARLES LINKIi, reside operation it is necessary to see the parts being cleaned so that nocombustion residues such as carbon or the like will be left, since in burners of this kindordinarily employed the carbon tends to collect.

Moreover it is possible with burners of the kind described to obtainonly a single direction of flame mainly downwardly after leaving the burner tip which often has certain advantages but more often leads to inconveniences. In the-improved burner .111 accordance Wltll the present inventionthe above-mentioned disadvantages are avoided.

The improved burner includes as its essential feature of a thin'plate for example of steel, nickel or similar material which at its end adjacent the burner tip is slightly hollowed out or'grooved. The other end of the plate is secured in suitable manner in a the one end of a rod which is screwthreaded at both ends, the free end of this rod projecting through the rear wall of the burner cas- 1n The lengths of the plate, of the socket and of the rod are such that when the rod is screwed home into the burner casing the grooved end of the plate projects beyondthe burner tip.

This forward end of the jects beyond the mouth of the burner can e cleaned with any desired amount'of care. It is to be observed that it is just at this part thatfcarbon and other residues from the combustion of the liquid fuel almost automatically settle. 'As is known the carbon resulting from this combustion is quite dense and requires thorough and repeated 31634 .1- 111g. j Q

Previously the whole burner had to be taken apart requiring quite a considerable time. Moreover provision of thegroove or recess on the plate 1n the front portion of the burner permits adjustment of direc-.

tion of the flame.

In the ordinary burners the plate isifa s tened, the liquid fuel flows over it and: the

jet of flame which leaves the burner is always directed downwardly. If a particular use of the flame requires such a direction,

the burner fulfils its purpose. It is clear however that whatin one case is .an-advantage 1n other cases is a d sadvantage, as

for example when an actualhorizontalfldirection of flame is required or the flame after leaving the burner is to be directed up wards j Since the plate of my present invention is movable it is possible to. direct" the flame to the desired extent. Accordingto the object For this purpose it is only necessary to rotate amilled nut at the end of the rod to movethe plate forwards and backwards and tovary the angle atwhich the jet of flame leaves the burner tip.

In the drawing is shown in longitudinal and vertical section one embodiment of the invention applied to a burner with a wide flame. I A s 1 A casing 1 is provided in its wall with an elongate, horizontally extending slot 15. "Within the easing an approximately horizontal, but slightly sloping plate 2 divides the space into an upper fuel chamber and a lower gas chamber. This slightly sloping plate 2 extends at its lower edge to proximity to the orifice 15, and forms within the casing walls passageways for confluent streams of liquid fuel and of compressed air which, mingling (with atomization of the liquid) emerge through theorifice Provision is made at 3 for the introduction into the upper chamber of fluid fuel, and at 4; for the introduction to the lower chamber of compressed air. An opening 5 is formed .in the upper wall of the casing for which a swinging closureG is provided, to the end that, as may be desired, additional streams .of flame-nourishing airymay passwith the-i intended the direction of the flame can be regulated as closely as desired.

stream of liquid fuel to the point of atomization at the lower edge of plate 2, and

thence through orifice 15, whence the flame springs.

Within the lower chamber a plate 7 is arranged. This plate 7 underlies 'theplate 2, stands opposite the lower face of plate 2, and forms the opposite walls of the air passageway leading .to the point of atomization, and to the orifice 15; J This plate 7 adjacent its forward edge 8 is provided with as'hallow, round-bottomed groove 9 which normally underlies the edge of plate 2, as is clearly shown in the drawing. The plate 7 is movable in the plane of its extent, and in. right-and-left direction transversely of the edge of plate 2, as seen in the drawing.

This mo'vability of the plate 7 has particular value. and importance in two respects.

First, by; minute adjustment with respect to the edge of plate 2, the size of the orifice through which the stream of compressed air emerges to effect atomization may be varied, and-the direction of the emerging stream of compressed alr maybe varied,

with consequent effect upon the direction of the. flame which springs from orifice 15. is movable, to the end that for purposes of cleaning it maybe extended through and beyond orifice 15 at least, its grooved edge may be so extended.

WVhen the edge ,ofv the plate is so-extcnded,

itmay, as-liasbeen said,be carefully and completely, cleaned.

' The drawingshows a convenient and effective mounting for p'late'7, bywhich the rmovement for the ends already defined may be effected. The plate 7 is carried in a :socketlt, and it will be understood that for 40 purposes of replacement and repair, "the in socket 14. The socket 141's carried upon at its opposite end through'the remote wall of casing 1. The remote end of rod 10 is screw-thread and carries an adjustable nut 11. "Additionally, it conveniently carries a knob 12. The-particular position of the nut 11 upon the rod 10, effected, of'course, by screwing it alongthe rod in one direction or the other, places a limit upon the right-toleft shift of plate 7. The knob 12 is merely a convenient handle to effect the shifting of the rod 10 longitudinally, and of the plate 7. An adjustable stop 13 carried by a casing I'may be provided. This stop is araccurately limitedj As shown inthe drawing, the position" in which the plate 7 finds itself, may not be changed, Shiftingfrom right to left is prevented by abut'menti of e'ver,1be manifest that'if nut 11 be shifted from" left to right along rod 10, the plate 7 may then be'shifted from right to left, and if stopv l3 be shifted from left to right, the plate 7 may'then also be shifted from left to right. r

The liquid fuel entering at 3 spreads upon theplate 2 and runs from its left hand lower "edge, Compressed air or its equivalent enters at4 and sweeps along the upper surface of plate 7 and across the lower edge of plate 2 from beneath, and thence through the mouth of the burner. i f the regulation of the groovedplate a bett'eratomization of. the liquid fuel is ob tained in consequence of-the regulated intersection of the current of compressed air with that of the combustible liquid.

"Having now. particularly described and "ascertained the nature of my said invention and 1n;what manner the same is to be performed, I declare that what I claim is: I
